AWS CloudFront URL Signature Utility

`aws-cloudfront-sign` is a JavaScript utility module designed to simplify the generation of signed URLs and signed cookies for Amazon CloudFront distributions. It addresses the historical gap where the official AWS SDK for JavaScript did not directly provide methods for CloudFront-specific URL signing, distinct from S3 signing. The package is currently stable at version 3.0.2, released in April 2026, with a release cadence that appears reactive to feature additions, bug fixes, and maintenance, rather than on a strict schedule. Key differentiators include its focused purpose on CloudFront signing, providing a straightforward API for both URL and cookie signing, and its compatibility with modern Node.js environments (v18+), including full TypeScript and ES Modules support since v3.0.0. While the AWS SDK for JavaScript now offers CloudFront signing capabilities, `aws-cloudfront-sign` remains a viable and actively maintained alternative.
